upgrade

I have a solution with several Silverlight Class Libraries and a Silverlight Application in it. I was originally built in VS 2008 with Silverlight 3.0. What changes do I need to make so that it builds using Silverlight 4.0? I already have VS 2010 and the Silverlight 4.0 toolkit installed.

When I opened the project it seems to have upgraded to .NET 4.0 in my ASP.NET Web Project but not the Silverlight projects. Pretty sure they are still building against .NET 3.5 and Silverlight 3.0.

Thanks.
